I've decided I'm going to try the loveland "Tour de Cure Colorado" by American Diabetes Association http://main.diabetes.org/site/TR?pg=entry&fr_id=2338
There are 2 routes that sound interesting:
Route A -- 50 miles: loveland to Drake and back
Elevation climb 1000 ft from 5000 to 6000.
Route B -- 75miles: loveland past Glen Haven and back
Elevation climb 3000 ft from 5000 to 8000.
I've been riding about 20-30 miles a week without difficulty. I know I'ld have to swap out my cassette as lowest GI is too high at 35gi.
The last time I road 50 miles was in high school, a day or two ago. Which would you do-- go safe with the 50 or go for the challenge and go for the 75? The 75 just tacks on 12 miles further than the 50 as that part of the route is the same, so there's always the option of bailing. This is a ride and not a race.
Thanks for your advice.
